Overpopulation exists and is a problem

My opponent believes that population increase is sustainable. He claims the human race will advance technological innovations to adapt to the increase in population. I aim to provide evidence against that claim and provide evidence, that overpopulation exists and is a problem. I believe that currently, our global population is growing quicker than we're able to adapt and innovate. before I present my argument I'd like you to visually see what overpopulation causes. Whether it's directly or indirectly, the fact of the matter is, overpopulation causes this kind of devastation: http://www.boredpanda.com... development-overpopulation-overshoot-global-population-speakout/ The effects of overpopulation. Everyone of these points has a link to overpopulation. The idea is simple; the more humans there are, the more humans there are to cause these problems. [1] Prices of gasoline are high because the demand has exceeded the natural resources. What happens when the net amount of energy we extract from the earth is shrinking? How then, does an economy grow exponentially forever if the one element it needs more than anything to flourish is contracting with time? As a demand for fossil fuels increases, so does the supply. The problem is, the supply is dwindling. Therefore the prices must be increased to make up for that. [2] Prices of fish are high because the oceans are being overfished. In just 50 years, the global spread of industrial scale commercial fishing has cut large populations fish. Around 85% of global fish stocks are over-exploited, depleted. When you consider that roughly 1 billion people rely on sea food, it's scary to think that the seas are being over fished to a point, where supply will soon not be able to meet demand.

A simple walk on any beach, anywhere, and the plastic waste spectacle is present. From the whale, sea lions, and birds to the microscopic organisms called zoo-plankton, plastic has been, and is, greatly affecting marine life on shore and off shore. Even the UN is warning that micro-plastics in the sea, is a growing threat to human health. Regarding micro plastics: http://www.independent.co.uk... [4] Rivers and bays are polluted because of high level of population and industrialization. Hundreds of millions of people do not have access to improved sources of drinking water, leaving them at risk for water sanitation and hygiene related diseases. Worldwide, 1.5 million children die annually from diarrhoea illnesses that are caused by unsafe water, poor sanitation, and inadequate hygiene. As global population increases, so does the contaminants found in water, from sewage and manufacturing processes. Regarding water pollution. http://overpopulationrisks.blogspot.co.uk... [5] Electric energy is insufficient because traditional sources of energy are limited. We simply can't sustain the growing demand for energy. Renewable energy sources are not powering the world yet. Until they do, we will continue to experience a large rise in gas and electric prices. Regarding price increase for gas and electricity: https://www.ukpower.co.uk... [6] Wild animals are disappearing because of over-hunting and environmental destruction. It's said we're currently responsible for the 6th mass extinction. 1,000 species are lost per year, mostly due to human-caused habitat destruction. Habitat destruction is caused by an ever growing population and a need to make room for farms. Regarding humans and extinction: https://www.theguardian.com... [7] Large predators have disappeared because of clashes with too many people. As human encroach onto habitats occupied by animals such as elephants. Elephants are not only being squeezed into smaller and smaller areas, but farmers plant crops that elephants like to eat. As a result, elephants frequently raid and destroy crops. They can be very dangerous too. The elephant human conflict: http://www.bornfree.org.uk... [8] Deforestation is a major problem. As the demand for farmland and wood increases, so does deforestation. About half of the world's tropical forests have been cleared. This is a problem for many reasons. One such reason is because we rely on trees to absorb carbon dioxide that is responsible for global warming. Without these trees the amount of carbon dioxide in the atmosphere is only going to become higher. Regarding deforestation: http://www.nationalgeographic.com... [9] Property taxes have increased dramatically because of a lack of suitable land. This makes Cost of living is very high. It's very simple. As populations grow, the cost of buying and running properties grow. This in turn leads to less luxurious living and in many cases increased poverty. Regarding housing and population increase: https://www.populationmatters.org... [10] Air pollution caused by overpopulation. As the amount of traffic on the roads increase, so does the carbon emission released by these vehicles. This, as well as industry cause poisonousness smog in cities. A great example is Chinas smog. Regarding Chinas smog: http://www.popsci.com... Conclusion: Overpopulation has a direct link to all of these problems. It is vital that we control overpopulation. If we do not then these problem will only get worse and many new problems will arise. I hope these points have proven to you that, we're not currently able to sustain many natural environments and species. The effect of overpopulation is damaging and is a concern currently. I will end with a quote from a source and that source: "We have a finite planet with finite resources. In such a system, you can"t have infinite population growth" http://www.pewresearch.org...
