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
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!!!

2. Talk about cause, effect of a certain type of pollution as well as solutions to this problem (water pollution)
Water pollution can be defined as the contamination of a stream, river, lake, ocean or any other stretch of water, depleting water quality and making it toxic for the environment and humans. It can occur in many ways: industrial activities like dumping waste which drains in the fresh water make it polluted; or agriculture activities like using pesticides, herbicides....; and the garbage that we throw everyday. And it effects seriouslly. First, water pollution truly harms biodiversity and aquatic ecosystems, makes the creature sick or even die. Next, it has very negative effects on human health because it is the cause of many diseasessuch as diarrhea, cholera, skin infections.... or dehydration because of lacking of fresh water. Besides, it destroys environmental landscape,..etc. But we can reduce water pollution in many effective ways like reducing the amount of water we use, having green agriculture or throwing rubbish into right places..... Water pollution is a serious problem, but we can solve it if we try hard!
