Question

the greatest threat is the belief that some one else will save our planet

Answer 1

    This point has come up due to an explorer, adventurer and entrepreneur called Robert Swan.  He traveled to the South pole and North pole on foot.  He examined the ecosystem and environment there.  He expressed that there is a  serious threat to Planet Earth as its environment is deteriorating. 

    Reasons for deterioration of Earth's health are be many. There is no control over anything and we don't care for it. People were involved in warfare, chemicals, selfishness, development without any concern towards other people, animals, birds or other nations. We stop the activities at the poles that are endangering animals and the ice rocks there.

    We can educate the people and invent new practices that will replace obsolete equipment and technologies. Change in the culture and selfish attitude are needed. Modernization that has taken place over the last few decades has to be converted into a harmless process.

   We live on Earth, so it is our duty to save our planet. If we think that a God will be born to do this, it is wrong. It is our mistake to spread pollution and expect someone else to clean it.  Each person should feel like the Green Lantern comic character and protect Earth.

  Due to our age old practices, industrialization and pollution of all types, many species of animals and birds have become extinct. Many species of fish in the seas and oceans have perished. The Snow Mountains around the world and at the poles are melting slowly. The ocean levels are increasing. The land near the oceans is getting submerged gradually.  Globally the temperatures are rising. The climate is getting hotter.

  Further, the monsoon system has changed. Forests are reducing. The seasons are irregular. There are acid rains here and there. There are droughts and floods at wrong times. The greenhouse gases have increased. The over powerful fertilisers are destroying the lands.

  The industries cause a lot of changes in the weather and environment around the location. The harmful gases deteriorate the atmosphere. The common people do obsolete and harmful practices due to innocence. The polythene and plastic bags and materials cause pollution.

  We have to use green or biofuels. We must use 4R (reduce, recycle, regenerate, reuse) methods. We need to use more of solar and other clean energies.  

   Many voluntary organizations and Social sites have raised the awareness. We have an Earth Day every year.  There are world conventions working on saving Earth.
 
   To bring out the change in everyone, nowadays we have competitions and lessons in schools. People exchange their views freely and look forward to positive improvements in the future. The discipline and control over the use of resources and environment is increasing.

  As we live on Earth, there is going to be some deterioration of the resources on Earth. As the population increased and urbanization has taken place, there has been a lot of imbalance on Earth.
 
  My wish and hope is that everyone thinks that it is his/her own duty to see that we use safe practices protecting our Earth. Being careless, because we are not going live after a century is mental illness and inappropriate thinking.
