2 minutes speech for asl topic environment

Answer 1

The biophysical environment is the biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. The biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment.

This article is about the biophysical environment. For other uses, see Environment.

The term environment is often used as a short form for the biophysical environment, e.g. the UK's Environment Agency. The expression "the environment" often refers to a singular global environment in relation to humanity.

Life-environment interaction

All life that has survived must have adapted to conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence any species, within any environment. However life in turn modifies, in various forms, its conditions. Some long term modifications along the history of our planet have been significant, such as the incorporation of oxygen to the atmosphere. This process consisted in the breakdown of carbon dioxideby anaerobic microorganisms that used the carbon in their metabolism and released the oxygen to the atmosphere. This led to the existence of oxygen-based plant and animal life, the great oxygenation event. Other interactions are more immediate and simple, such as the smoothing effect that forests have on the temperature cycle, compared to neighboring unforested areas.[citation needed

Answer 2

Good morning to the Excellencies, my respected teachers and my dear friends. As we have gathered here to celebrate this occasion, I would like to speech over Environment. To run the life in healthy happy way, we all need a healthy and natural environment. Continuously increasing human population adversely affects the forests. Human beings are cutting forests to a great extent for making their home to live securely however they do not think of the problems arises due to the lack of forests. It completely disturbs the natural cycle between environment and life on the earth. Because of the over-population, the number of various chemical elements is increasing in the atmosphere which ultimately causes irregular rainfall and global warming. We cannot imagine the negative effects of global warming over the climate and lives of human beings and other living species.

According to the research it is found that the perennial snow mountains of the Tibet were totally covered by the thick snow in the past however those thick snows are getting very thin day by day over last few decades because of the global warming. Such condition is very dangerous situation and indication of end of life on earth which needs to be taken very seriously by all countries worldwide. It is very true that climate change goes very slow however slow continuous process is very dangerous. Because of the regular changes in the environment physical structure of the human beings and other living species has been changed from generation to generation. Increasing human population needs more land for agricultural cultivation and living purpose which force them to cut more trees and forests so the deforestation has its own dangerous side effects.

Increasing level of industrialization has countless harmful effects on the atmosphere because of the poisonous chemical emissions and dangerous wastes drainage in the big water resources such as Yamuna, Ganga, and other rivers. The ever changing (negatively) environment is not the issue of only some countries or government; it is the issue of whole human fraternity because we all are the reason of this negatively declining environment so we all are responsible to save our natural environment for the healthy survival of life on the earth. Protecting the atmosphere is the matter of high importance for all the present and future generations of mankind. The main purpose of my speech today over the environment is only to increase the public awareness among common people about the reasons of declining environment as well as need of healthy and natural environment for the life on earth. So, it is my humble request to all of you that please contribute to save your environment.
hope it helps you
