The life on Earth today have been endagered and altered by the actions of humans. Human alteration to the Earth is substantial and growing. About one-third of the land's surface area has been transformed by human activity. The concentration of greenhouse gasses have increased 30% since the beginning of industrial revolution orginating problems such as global warming. Global warming blazes dasators such as the melting of the ice caps in the North and Southern poles, changing the Earth's temperature, destruction of the ozone layer, extinction of species, various deaseases and plagues.All these problems affect the biodiversity of the planet as all species are conneted to each other through food webs.
More than half of all accessible surface fresh water is put to use by humanity. Humans pollute the world by adding the factory wates, fertilizers and organic wates in to river, lake or any other water body. This affects the aquatic life and then through the food web the whole life in the biospere. Many aquatic, land and air species have gone into extinction because we pollute the land, water and air by toxics and other form of pollutants.
Moreover, the melting of the ice caps in the Northern and the Southern poles should not be taken as a light concern by the global population. Over the
past five years, studies have found that melting Antarctic ice caps contribute at least 15% to the current global sea level rise of 2mm in a year. It is thought that over 13,000 sq km of sea ice in the Antarctic Peninsula has been lost over the last 50 years. Melting in the Antarctic Peninsula removes sea ice that once held back the movement of glaciers. As a result, glaciers flow into the ocean up to six times faster than before. If this pattern continues, the Earth could be swallowed by the oceans in about 50 years. All the more, it means that the species in living in the North, such as penguins and Polar bear are endangered because they cannot adapt to the changing environment conditions and the also becuase they are loosing their land on which they live, walk and prey to sustain thier life.

Change in temperature is another issuse that should disturb our peace and influence us to take action. Global warming is increasing the Earth's temperature constantly. The Earth's
temperature increased from 0.74 degree celsius to 0.18 degree celsius in the last century. This cause enormouse problems such as the extiction of certain spieces who cannot adapt with the rising temperatures. The extictions causes problems such as the increase in population in certain species while the decrease of population of the other; causing disruption in the food web. For example, if a number of Giraffe's die, their predators, the lions, will suffer scarcity for food and die eventually. However, the plants that the Grirafee's eat will rapidly increase in number. This causes distrubace to the balance of the earth and challenge the biodiversity of the Earth. The Ozone layer is an area in the Stratosphere that abrobs 97-99% of the suns ultraviolet radiation which is potentially damaging to life on earth. Every 1% decrease in the earths ozone shield is projected to increases the amount of UV light exposure to the lower atmosphere by 2%. This information should bring up concerens in every human mind as the Ozone layer is depleating due to the actions of mankind. This deplation affects the health of all in the biosphere the increase of skin cancer in the world today is because our bodies are more exposed to Ultra violet radiation. The health of animals are also challenged. Frogs are amphibians that even lived through the ice age, yet they are endangered today because they are affect by the toxic in water and air as well as UV radiations. This is a very negatively affect on the biodiversity of the Earth, as more and more animals are entered into the endangered list.
We are supposed to be the stewrads of the Earth, yet we have acted to destroy our planet. If we don't act against our own action and correct the mistakes that we have made, we will cause suffering for our future generations and deplete the biodiversity of our beautful planet. The destruction of biodiversity means the detruction of our planet. Our Earth will no longer be a friend. We can rectify our mistake by starting to do simple things like taking the bus to school instead of our cars, walking to close by places, recycleing, reusing and reducing garbage. We can still help our Earth recuperate if we work together and live with consideration towards the environment and all the life in it.
First off, I really like the graphics that you used. They went well with the blog entry as well as helped the reader understand the size of the melting the ice cap in the first picture. There are a few spelling errors but thats okay! :) We all make them !! The change in temperature this is causing is affecting every single organism on this planet. It's really sad to see that people don't realize how much trouble we're all going to be in if we don't act fast on helping to slow down global warming and keeping the environment healthy and at an equal balance.
ReplyDeleteI agree with what you said in your post about the ozone layer being destroyed by all the harmful gases (especially CO2) that are being emitted into the atmosphere. The actions of the people around the world, fueled by ignorance and greed, have put is in this position and some people say it's already too late to do something to save our planet for future generations. On the other hand, I know there is nothing that can be done to take back everything we've done, but there is always room for improvement to change the way we live.
Really good blog post. I found it very very informative!
WOW! what a nice blog. you have nicely out it together and it flows ver well. I see some spelling errors but thats okay, even i make errors. I like how you used pictures to help the reader understand the information correctly. You have brought up alot of good points in this blog. The funny thing is that even though we understand how our human activites are causing global warming and hurting animals, ecosystems, us and our future generations we don't really make an effor t to reduce or stopour activites. Global warming is happening right infornt of us and were just being ignorant about it. I found that its very hard to change a humans nature and if we want to save our world the government has to take action and maybe band plastic bottles to start with. Thank you for posting this blog it helped me realize alot of things and learn alot.
ReplyDeleteAwesome post Vanessa!
ReplyDeleteI completely agree with you that global warming has become a very important issue and that if we don't act soon, it can destroy our planet! Every time I hear or see the words "global warming", I actually become quite scared, because this is now a big reality and it is all happening right now, right this second. If humans do not pick up their pace to improve the planet we live on, who knows what our earth would be like in 50 years..but you suggested some great things for people to consider, such as taking the bus to school and recycling. People should pay more attention to these suggestions because these suggestions can definitely make a big positive difference in our environment.
