More than 50% of all aquatic species were wiped out and eliminated many land animals and plants, most notably all the dinosaurs except for the birds. The causes include climate change which occurred due to volcanic floods in India as a consequence of a giant comet Collison in the Gulf of Mexico (Wake, D.B., Vredenburg, V.T. and wakelab, 2008). Evidence for this can be supported by the fact that Iridium a very rare element found on earth but commonly found in extra-terrestrial objects and a layer of iridium was found on the coast of Mexico. The crater in Mexico is similar in size to an object with a radius of 5km, which could have collided there (Reece,
The model eliminated the Glass-Steagall legislation, which prevented large firms from making risky financial investments. Deregulation is the key to runaway equality and deregulation allowed it to happen (Leopold, p. 35). Lastly, reducing government social spending eliminated many safety net programs that aided and protected workers and families during tough economic times. The cutting of safety net programs does the exact opposite of what the Better Business Climate model promised. The model is supposed to bring renewed prosperity to the United States but it brought more inequality and stripped safety net programs that actually helped most Americans.
“Global warming is too serious for the world any longer to ignore it’s dangers or split into opposing factions on it, Tony Blair.” The disregard by scientists of global warming does not remove the problems of disturbing the balance of habitats, negatively affecting the human body, and affecting the natural forces of nature, making us doubt the negation of global warming due to its horrific effects. My rebuttal coming from a site that negates my position that global warming is, in fact, real, and a serious problem. In an article coming from Conserve-energy.com, it states in years in the past artic ice has “increased by 50%” which negates the concept of a gradual warming in temperature around the earth. This article also so presented studies
Homero Castro Ms. Cabaj English IV, 3rd period 12 February 2018 Global Warming Global Warming is affecting the entire world. The issue of global warming is important because it’s affecting everyone. This problem is controversial because some people believe that that global warming isn 't real and others believe it is. There is evidence that global warming is real because some scientist agree that the earth 's rising temperatures is due to all of the pollution. My opinion on it is that it is clearly real and we need to do something to stop it.
The eruption of Mt. Vesuvius and the subsequent burial of Pompeii is one of the greatest disasters known to man. The volcano erupted in 79 BC after a major earthquake in 62 BC woke up the mountain. The towns of Pompeii, Herculaneum, Boscoreale, and Oplontis were buried early morning on August 25, 79. Oplontis and Boscoreale were the first towns to be destroyed; they were buried in the first weak lava flows and explosions.
Also, recent estimates suggest that 1-2 percent of Madagascar 's remaining forests are destroyed each year, and that a staggering 80-90 percent of Madagascar 's land area burns each year (Kremen). Cyclones originating from the Strait of Mozambique or the Indian Ocean are distinct possibilities. In addition, flooding and droughts, neither of which are not uncommon, are linked to other environmental issues with the spread of disease and swarms of locusts (Miller). With its rivers running blood red and staining the surrounding Indian Ocean, astronauts have remarked that it looks as if Madagascar is bleeding to death. This insightful observation highlights one of Madagascar 's greatest environmental problems—soil erosion.
First of all, how did this happen initially? Well as I stated, an earthquake hit Japan in 2011 causing a tsunami measured at 10 meters high at it’s peak. This tsunami alone had 19,000 casualties. This tsunami was able to destroy the cooling and power supply of three nuclear reactors on March 11. This caused the cores to melt over three days, therefore releasing radiation all over the world.
National Geographic states “by such things as climate change, an intense ice age, volcanoes, and that space rock that smashed into the Gulf of Mexico 65 million years ago, obliterating the dinosaurs and a bunch of other species. These events are known as the Big Five mass extinctions, and all signs suggest we are now on the precipice of a sixth.” Which means we are seeing signs of the next big mass extinction in the future. My position of this is that I am for the thought of the animals increasing over
“I fear for our future. Our planet earth is threatened with an ever expanding population and only finite resources. We need a plan B.” - Quotation by Stephen Hawking, renowned physicist. Our world is dying. We have been mining coal for only two hundred of our 200 000 year existence as a species, yet we have already caused irreparable damage to the environment.
Our planet could be hit by an asteroid or comet that could destroy the human race. This happened millions of years ago. When the dust settled, it trapped greenhouse gases into Earth’s atmosphere. Earth became extremely hot and most plants died, along with all dinosaurs. A volcano could have erupted which would have caused the same effect.
