Question

what will happen if plant and animal disappear from the Earth surface can the human being survive under such a situation why is biodiversity necessary and why should it be conserved

Answer 1

IF PLANTS AND ANIMALS WILL DISAPPEAR FROM THE EARTH THEN EVERYTHING WILL BE DESTROYED.HUMAN BEINGS TOO WOULD NOT BE ABLE TO SURVIVE ON THIS PLANET.

Answer 2

Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. There would also be no rain without trees since trees absorb water from the soil and release it through evapotranspiration. Water vapor released through evapotranspiration is the major mechanism by which air is remoistened. Forests act as giant air filters for the world. Trees purify the air by absorbing pollutants such as sulfur dioxide and nitrogen dioxide, reducing pollution. Trees also help prevent topsoil erosion because they break the force of wind and rain on soil, their roots bind the soil, and their decayed, falling leaves are absorbed by the earth and enrich the soil. Trees conserve rainwater and reduce water runoff and sediment deposit after storms.Additionally, trees provide a supply of lumber, seeds, and fruit. Further, dead trees that fall and get buried in the soil eventually provide fossil fuels such as coal and petroleum products, among other things. Trees can also act as noise filters. Trees muffle urban clamor almost as well as walls do. Trees planted at strategic locations can decrease loud noises from airports and highways.

Benefits of Trees;

Here are 22 of the best reasons to plant and care for trees or defend a tree’s standing:Trees combat climate change

Excess carbon dioxide (CO2) caused by many factors is a building up in our atmosphere and contributing to climate change. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air. In one year, an acre of mature trees absorbs the amount of CO2 produced when you drive your car 26,000 miles.

Trees clean the air

Trees absorb odors and pollutant gasses (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.

Trees provide oxygen

In one year an acre of mature trees can provide enough oxygen for 18 people.

Trees cool the streets and the city

Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.

Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.
