Effects of environment on human health

Introduction

Sensible quality natural environments offer multiple edges to health and well-being. In contrast, air pollution, noise, poor quality water, chemicals, radiation, and environmental degradation cause numerous impacts on human health.Humans impact the environment in several ways. Common effects embrace weakened water quality, redoubled pollution and greenhouse gas emissions, depletion of natural resources and contribution to global temperature change.

World biggest environmental problems

These five megatrends present major world threats for planet Earth — problems that must be solved if the globe is to remain a supportive environment for humans and alternative species. DW looks at causes and possible solutions.

1. Air pollution and climate change.

  Re-emits infrared-wavelength radiation, leading to warmer air, soils, and ocean surface waters - which is good: the world would be frozen solid without this. We breathe air to live and we breathe to be direct impact on our health. The Breathing in polluted air puts you at a higher risk for asthma and other respiratory diseases.

2. Deforestation.

Problem: Species-rich wild forests area unit being destroyed, especially in the tropics, usually to form approach for cows farming, soybean or vegetable oil plantations, or different agricultural mono-cultures.

3. Species extinction.

Problem: toward land, wild animals area unit being hunted to extinction for bush-meat, ivory, or "medicinal" product. At sea, vast industrial fishing boats equipped with bottom-trawling or purse-seine nets clean out entire fish populations.

4. Soil degradation.

Problem: soil compaction, overexposure to pollutants, land-use conversion - there's a long list of ways that soils are being damaged.

5. Overpopulation.

Problem: Human population continues to grow rapidly worldwide. Humanity entered the 20th century with 1.6 billion people; immediately, we're about 7.5 billion. Estimates put US at nearly ten billion by 2050. Most of the growth is going on on the African continent, and in southern and eastern Asia.
