Pollution of rivers/lakes
Nutrient pollution builds up in our nation’s lakes, ponds, and streams. Lakes and rivers are common sources for drinking water supplies. Both algae and high nitrate levels cause problems in sources of drinking water. Nationwide, violations of state nitrate limits in drinking water doubled over a 10-year period.
How It Happens
Here are the few major causes of water pollution: Sewage And Waste Water,Sewage, garbage and liquid waste of households,agricultural lands and factories are discharged into lakes and rivers.Industrial waste is discharged into lakes and rivers by using fresh water making the water contaminated.
How to Prevent
Climate change is a change in the pattern of weather, and related changes in oceans, land surfaces and ice sheets, occurring over time scales of decades or longer. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth’s climate system and caused change on a global scale.
How It Will Affect
Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats
Promising ways to mitigate climate change are what we call “natural climate solutions”: the conservation, restoration, and improved management of land.Also transferring to renewable energy methods and Reduce water waste are key steps for stop climate changes.
Human Wildlife Conflicts
As we urbanize and develop more, natural habitats for wildlife shrink, often leading to fragmented forests. With increased habitat loss, our native wildlife is forced to adapt and seek food and shelter in urban areas. Read More..
How to Overcome
To overcome human-wildlife conflict Conducting roadshows at habitat hotspots to raise awareness and educate members of public on human-wildlife co-existence by working closely with Town Councils.Encouraging student projects that will aim to address the root cause of the problem Promoting preventative measures to address conflict instead of culling.
