All of us know how important it is to protect our environment and we hear about the negative effects that our lifestyles have on nature and our world every day. A very serious result of our careless living is pollution. One of the main effects of pollution is global warming, for example, which causes the changes in our climate and makes temperature rise. This leads to many problems for humans, plants and animals.
Környezeti szennyezés és globális felmelegedés
Greenhouse effectIn the last 100 years the Earth’s surface has warmed up by more than half a degree, this change could cause rising the sea levels by up to one and half meters by the year 2030. The Greenhouse effect is caused by polluted atmosphere which was polluted by carbon dioxide from fossil fuels and chlorofluorocarbons.The best protection is to stop producing these gases and destroying rain forests. It is worth replacing old power plants with nuclear power which reduce the damage. Also nuclear power has its disadvantages, in this case there are alternative sources of energy : hydropower, solar power, geothermal etc.
Ways to fight air pollution are straightforward: be less dependent on polluting transportation - ride a bike more and use the car less if you can’t have an environmentally friendly one. Buy less new, non-recyclable products and check if they are environmentally friendly or not. Nature has a way of keeping our water supplies clean, but we are making this more and more difficult. Cities and their industries dump waste products and chemicals into the seas, which is not only destructive for humans, but also for all other living beings.
Ózonréteg és ózoni lyuk
Ozone HoleThe ozone gap is thinning at a rapid speed. It is a layer which protect us from dangerous UV rays, these could damage the life on the Earth.Possible effects of the sun’s UV rays:Eyes: cataracts and blindnessSkin: premature aging, skin cancer and wrinklingImmune system: they brake down the immune systemCrops: they could interrupt the process of photosynthesisSea life: growth of plankton which are a vital part of the food chain in the world’s oceans. The areas of largest ozone hole are Antarctica, South America, Australia, New Zealand. The main destroyers are CFC and halons which are used in refrigerators and air conditioners.

Környezeti védelem és jogi keretek
Környezeti védelem: -Magába foglalja mindazokat az intézkedéseket melyek célja az emberi populáció védelme, a természetes és mesterséges környezetének megóvása. -Az állam a jog eszközével tiltja és műszaki szabványokban rögzíti a kibocsájtható szennyeződések mértékét a levegőben, vízben, talajban lévő anyagok határértékeit. -Támogatja a környezetvédelmi kutatásokat, ösztönzi az anyag-, és energiatakarékos környezet kímélő eljárások bevezetését és létrehozza a környezet és természetvédelem intézményrendszerét. -A bíróságok fedezetül szolgálnak a károk enyhítésére, illetve a károsítás csökkentésére ösztönzik a károkozókat. -Minden állampolgár felelőssége a környezet megóvása, hétköznapi szokásaikat úgy kell kialakítaniuk, hogy a környezeti károk csökkenjenek.
Water and land pollution are connected many times. If you use natural and biodegradable products for farming, you can prevent poisonous substances like pesticides, insecticides and artificial fertilizers from getting into our soil, into the plants we and the animals eat, and also into our water sources. Recycling our waste is also an important step to take to stop land pollution. Garbage that is non-biodegradable and does not easily rot into organic matter should not be piled up on the landfills where cities transport their waste. They stay there for thousands of years and pollute our earth and the crops we eat. Deforestation is also a kind of land pollution. We need trees to absorb carbon dioxide from the air and produce life-giving oxygen, while forests are the home of many animals, birds and insects. We also use wood for housing, furniture and heat. While we are cutting down trees for construction, farming and mining, we don’t plant new trees.
