Pollution of rivers/lakes


Nutrient Pollution

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.

Climate Change


Climate Change

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.
