Does the world have good environmental practices?

Over that past few centuries, the earth has become more and more badly polluted, and the world on the whole has been having poorer and poorer environmental practices. This has contributed to the rise of carbon emissions around the world, as well as the rapid rise in global temperatures in the past few centuries.
Before the mass mechanisation of labour, before the Industrial revolution, and before mankind started their astonishing development and technological advances, the temperature for the first nineteen centuries was rather constant, only fluctuating within a small range of 0.2 degrees Celsius, however, after the end of the nineteenth century, it suddenly shot up by about 1.2 degrees Celsius.
Firstly, looking at the big countries and the different superpowers in the world, we can see how poor the environmental practices of such countries are. If we take a look at China, for example, China’s air pollution in Beijing was so bad that they even had to stop all cars from traveling on the roads for a few months before the Olympic Games, just so that the air would become less polluted. This clearly shows how bad the usual state of pollution the country is in normal cases. Now the Olympic Games is over, China has reverted back to its old ways. Instead of keeping up the good effort that they have been putting in to this Olympic Games, they have let their efforts go to waste. China also has been shown to have one of the highest carbon emission rates in the world.
Another possible case study would be America. America is also another country which is leading in the carbon emission race. Since it was adopted for use in 1997, every single developed country has signed it, with many other developing countries signing it as well, some of them signing it because of America’s influence. However, America itself did not sign the Kyoto protocol as being a capitalistic country, it was unwilling to let these obligations obstruct their inflow of wealth.
Looking at the less developed countries, we can also see some countries like Brazil which have extremely poor environmental practices. Because of the physical and geographical conditions in Brazil, many multi-billion corporations such as MacDonald’s set up branches and farms there. One major problem is cattle grazing, where large plots of land are used to rear cattle. By rearing cattle, the fertile ground gets drained and quickly becomes barren. Thus, these companies start to buy more land and use up more resources. When they run out of land, the start to cut down the Amazon forest, and eat into the land previously occupied by the forest. This not only causes the land to be barren, but also contributes to the deforestation rate. Moreover, cattle tend to give off methane during digestion, which also contributes to global warming as it is a type of greenhouse gas. Despite the pressures that the government faces from environmental groups and other countries around the world, they are unwilling to give up the money that they can earn from selling land to these companies.
Another case study which we can look at is Indonesia. Indonesia usually adopts the slash and burn tactic in order to continue having fertile land for farming. While this may be useful in the short term, it is definitely not beneficial in the long term. Firstly, it depletes the natural resources that the country has and does not fully utilise the resources. Secondly, it leads to a large scale air pollution, as can be witnessed right here from Singapore. Every year, when the forest fires start in Indonesia, Singapore would be adversely affected, despite the large distance between Indonesia and Singapore. The air in Singapore would become very hazy and polluted, and this situation would usually stay for about a month or so.
Thus, I can safely conclude that most countries on the whole generally do not have good environmental practices. While many of these countries have come up with brilliant plans, it is rare to find one that is really put into action instead of just hearing the governments speak about them.
