Have you ever asked yourself what ways of communication you will be using in the future?
I strongly believe there will be huge changes in the way we communicate.
Presently, we often meet face-to-face, send emails or chat online to work on our group projects.
But it’s possible that in the year 2030, we’ll be having video conferences with 3D images and Hololens Virtual Reality Glasses to interact with these people.
When we want to ask our friends to get some drinks, we often contact them by phone or social media.
However, in 20 years, super-smart phones, which can read your thoughts and automatically transfer them into text or voice messages, will be replacing those methods.
Besides, I guess telepathy will be especially popular then.
And I bet in 40 years, we will be able to understand what our pets are thinking with the help from some smart devices.
That will certainly be very amazing!!!
Nowadays, one of the biggest problems human are facing with is water pollution. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment. A lot of causes are responsible for this issue. And they lead to extremely bad consequences. I’d like to explain more in the following paragraphs.
Some typical causes of water pollution are Industrial waste, Sewage and waste water, Mining activities, Accidental Oil leakage, Burning of fossil fuels, Chemical fertilizers and pesticides, … These agents contribiute to water pollution.
And the consequences? Of course, it is human health! Human are likely to get into trouble with some diseases such as hepatitis by eating seafood that has been poisoned. Water pollution also brings about the death of aquatic (water) animals, Disruption of food-chains, Destruction of ecosystems.
In conclusion, water pollution is a alarming problem that needs to be solved as soon as possible. The sooner we solve it, the more healthy we are.

Causes of water pollution
1) Water pollution may be caused by the intentional or unintentional disposal of hazardous chemicals and materials into a body of water.
2) Rainfall may cause polluted landscapes to disperse their poisonous materials into the water and poison the surrounding water.
3) Water pollution may also be caused by specific points or contributing factors such as large factories, oil refineries, construction sites, chemical waste management facilities, dump sites and other large scale operations that store/produce large amounts of chemical/hazardous waste.
Effects of water pollution
1) Toxic rainfall can occur in areas where water and/or air is polluted with toxic chemicals and materials.
2) Polluted water can lead to sickness, disease, infections, deformities and even death among animals and plant life.
3) Once water becomes polluted it can affect people and animals either directly through consumption or indirectly through food sources, land degradation and the overabundance of plants and algae which can cover the surface of various bodies of water making it undrinkable and affecting the animals that live in that body of water.
Solution:
The most critical step to prevent water pollution is to adopt appropriate waste management policies. Setting up of wastewater treatment plants can resolve this issue and hence we can protect our natural water resources from contamination and embrace an eco-friendly life.
HOW YOU CAN HELPIf you would like to limit the amount of pollution you produce and thus help keep the oceans, rivers and lakes clean there are a number of things you can do.
- Replace your air fresheners with eco-friendly candles, incense and/or potpourri
- Purchase environmentally friendly cleaning products that do not harm the land if they happen to be flushed or emptied into a drain
- Reduce the amount of power you use and purchase energy saving light bulbs and appliances. This helps reduce the amount of emissions being released by utility companies and your own home products.
- Conserve your water usage and don’t leave water running when you are not using it
- Reduce, recycle & reuse materials that you have purchased. Plastics and papers may be sent to the recycling bin while some of your glass materials may be able to be reused or re-purposed
- Make sure non recyclable waste is contained properly so that it does not spill into the land, street drain sewage drain
- Purchase local food that has been grown from healthy agricultural farms that don’t use polluting fertilizers and pesticides
- Purchase eco-friendly lawn fertilizers and pesticides for your own lawn in order to prevent your lawn from becoming toxic and prevent possible hazardass chemicals from entering street drains
- Recycle old clothing by giving it away to shelters and non for profit re sellers. Not only does it lower the amount of garbage you produce it also allows you go give to a cause and help the community
- Use a reusable grocery bag rather than the plastic bags offered at grocery stores when shopping for food to minimize your plastic waste
- Eliminate unnecessary mail and have your bills sent to you by email. This helps protect the trees and reduce the amount of paper you have to dispose of later
The key to environmental sustainability is thinking globally and acting locally. Pollution prevention is about making smart choices–both in what we buy and in how we use products. It involves looking at the causes of waste and pollution and figuring out how to prevent them.
Due to the number of people in attendance and the many activities taking place throughout the day at a school, larger quantities and more types of waste are produced at schools than in homes. Students, administrative staff, teachers, janitors, and contractors all use energy, water, and even hazardous chemicals, throughout the school year. Therefore, schools are a great place to introduce pollution prevention (P2) ideas on how to reduce or eliminate pollution and waste, which can be harmful to humans and the environment and costly to school budgets.
Where is waste generated in schools?
Energy: used in lighting, office machines, heating, air conditioning, transportation
Hazardous chemicals: found in cleaning supplies, aerosol cans, paints, science labs (mercury), art classrooms, janitors' storerooms
Pesticides: used on school grounds, gyms, kitchens, locker rooms
Water: used in bathrooms, kitchens, locker rooms, sinks in classrooms, outdoors
How can your school prevent pollution?
All students, teachers, administrators, and janitors should ask themselves if there is a better way to do their job–a way that will not create waste. In other words, everyone at the school should adopt a "less is best" attitude.
Some ways that students, teachers, and school administrators can prevent pollution at school include the following:
Bike, walk, or share rides to and from school.
Request that drivers of school buses and cars turn off their engines while they wait to pick up or drop off students.
Use less toxic glues, paints, markers, and other materials.
Start a book exchange.
Collect unused school supplies at the end of the year for reuse next year.
Buy unbleached, recycled paper.
Organize a tree-planting event on school grounds, or organize a school-ground naturalization project to create opportunities for outdoor learning through hands–on experience.
Use both sides of paper.
Take a "litter-less" lunch to school, by using reusable containers and a re-usable lunch bag.
Use refillable pens, printer toners, and ribbon cartridges.
Turn off machines when they are not in use.
Organize a paper, glass, plastic or metal recycling project.
Eliminate the use of pesticides and chemicals on the school playing fields.
Encourage students to implement pollution prevention principles that they have learned at school in their homes.
Form a pollution prevention team.
Celebrate Environment Week and participate in a community event.
