Thus, it is the duty of the human beings to take care of our environment by preventing pollution and avoiding deforestation.

The types of pollution which are caused due to humans are:

 

Air pollution:    

             Air pollution occurs due to the increased number of vehicles, increased number of waste discharge from the industries, burning plastics and so on. Thus, humans must take step to control air pollution by following ways.

  1. Instead of burning papers, glass bottles, plastics try to recycle them which conserve energy and reduce production emission.
  2. Plant at least one tree at your neighborhoods.
  3. Try to use solar electricity at your homes.
  4. Choose not to smoke anywhere outside the smoking area.

 

Water pollution:

                     Just like air pollution, water pollution is also one of the major threats caused by human beings. Water pollution which are caused due to several factors like mixing chemical wastages from the industries, polluting the ponds and lakes, etc.,

       The ways to control water pollution are:

Plants prepare their own food with the help of the process called photosynthesis. The main foods for the plants are water, sunlight and healthy soil. Reproduction is of two types in plants. Asexual reproduction takes place with the help of single parent whereas sexual reproduction takes place by the fusion of gametes resulting in offspring. Plants main responsibility to our environment is to inhale harmful carbon dioxide and exhale fresh oxygen. Also, we get various types of foods from the plants such as fruits, vegetables, leafy vegetables, etc.,

Animal life:

           Every animal has unique characteristic and feature. The appearance of every animal is different from another.
