Write a speech on Climate Change is due to Human Activities'
Answers
Answer:
Due to the basic physics of heat-trapping gases and an exponential rise in population and energy consumption, humans have become a force of nature. Clearly, this is a topic with enormous political, socio-economic and emotional dimensions, but the scientific results show clearly that:
Human activities, particularly the combustion of fossil fuels, are altering the climate system.
Human-driven changes in land use and land cover such as deforestation, urbanization, and shifts in vegetation patterns also alter the climate, resulting in changes to the reflectivity of the Earth surface (albedo), emissions from burning forests, urban heat island effects and changes in the natural water cycle.
Because the primary cause of recent global climate change is human, the solutions are also within the human domain.
Because we understand the causes of climate change, that paves the way for effective solutions to be developed and deployed.

Answer:
Good morning to my respected teachers and my friends. Today I want to present a speech on climate change.
The average temperature of a region for a long period of time is considered to be that region’s climate. The people who live in that region get used to the conditions of the climate.
Generally, the climate of a place does not change drastically, but it takes years to change.
As the climate of a region is dependent on certain factors; they are, the location of the region (mountainous region, seaside, and plain land), the average rainfall in that region in a year, the amount of sunlight it receives and many more.
These factors help in detecting the climate of a place. Weather and climate are two different factors. The weather can change within a few minutes or a few hours, and the climate does not change for about a period of 35 years.
It is the climate which makes a suitable habitat for the natural vegetation and the animals. The climate of a place allows a certain species of plants to grow in a region and survive. Some plants require less water and more sunlight and some plants require more water and less sunlight.
The climate of a place makes it easier for the plants to grow and survive in its favourable conditions. After the plants, the animals look for their suitable habitat. The animals which can survive for several months without food and water are comfortable staying in the regions which do not have sufficient food and water.
The main role behind the climate and its variations is played by the sun. The sun’s rays fall on different regions in a different manner. As the shape of the earth is round, the sun’s rays do not fall on all the regions equally.
The equatorial region receives the direct rays of sunlight, and this is the reason the equatorial region remains the hottest region throughout the year. The polar region receives the indirect or slanting rays of the sun. This is the reason the polar region remains snow-covered all the year-round.
Global warming is becoming a serious issue. It is coming in the way of every natural habitat. Global warming is gradually changing a region’s average temperature and rainfall.
The regions which had a moderate temperature all the year round now have high temperatures. The regions which received an average amount of rainfall are now either receiving a high amount of rainfall or scanty rainfall.
Climate change is affecting the natural vegetation and animals very much. Plants are dying due to improper amounts of sunlight and rainfall. The animals are suffering as they are not getting sufficient supply of food.
Despite having all these difficulties, the plants, animals, and human beings are trying to adjust with their new climate as nature has the ability to adapt and survive. The species which are having difficulties to survive are dying and becoming extinct. But the species which are adapting themselves well, are survivin
