Many peopleuseelectricity ocook and to heat their homes. (/e also use electricitvto power somevehicles,and we useoil to makegasoline o power carsand other vehicles.The problem is that these ossil uels cannot bereplaced,so when we haveused them all, they willrun out. They are called non-renewable esourcesand we are using them too quickly.

PollutionSometimeswe make our resourcesdirty.This is calledpollution.S(/e pollute the air when we use fossil fuelsto make energy ike electricity. Wepollute water whenwe put waste nto it.

GlobalWarming'Whenwe use ossil uels we make a gascalledcarbondioxide. Scientists hink that we areputting too muchcarbon dioxide into the air.The carbon dioxideincreaseshe greenhouseeffectand Earth getswarmer.This is calledglobal warming.

Extreme eatherScientists hink that global warming is changing ourclimate and making the weathermore extreme.This isa problem for people,animals,and plants.Hurricanes are getting more dangerous. n 2005, ahuge hurricane hit New Orleans n the USA. About2,000 peopledied, and most of the city was looded.There aremany rivers n Bangladesh. here are alwaysfloods in the rainy season, ut the floods are gettingworse.

People died and many morepeoplewere sick.About 336,000 peoplehad to moveaway to new homes. Scientistsare working hard tomake nuclear power stationssafer.

Solar nergyAnother way to make electricity is to use the heatfrom the sun. Solar power stations only work wellin placeswhere it's very sunny all year long.In many countries,people use solar energy fromsolar panels o heat water in homes, offices,andswimming pools, and to power watches,calculators,and road signs.

Germany, forexample, makes 6o/o f its electricity in wind farms. Allaround the world there are more and more wind farms.GeothermalnergyGeothermal energycomes rom the heat that is trappedunderground. Hot water and steam from undergroundcan be used to heat buildings, and to make electricity.In Iceland there is lots of hot water underground.Geothermal power stationsmake about 25o/o fIceland's electricitv.

For short journeys,we can walk or cycle.This is also better than sittingin a car becauseexercise s good for us.W'ecan sharecars or usepublic transportation for some ourneys.\Wecan try to use small cars because hey use essfuel than big ones.We should also reduce the number of vehicles hatwe make,becausewe use ossil uels to power thefactories where we make the vehicles.Some people ry to fly lessoften, and if they have ofly, they do something called carbon offsetting. Theyfind out how much carbon dioxide their journey willproduce.Then they pay to plant enough rees o useall the carbon dioxide that the journey made.

Reducinglobal armingIn the daytime, plants take carbon dioxide from theair to make their food.This helps ro reduceglobalwarming. It's one of our planet's natural ways toreduce carbon dioxide.PlantsnDangerPlants need clean air and water to grow - polluted airand water can damage hem. Global warming is alsoa problem. Someplants cannot grow in their usualplace if the temperature gets too high, or if there isextreme weather like floods.\il7e re using too many trees.Big internationalcompanies cut down huge numbers of trees for woodto make furniture or paper. Sometimes they cutdown trees n rainforests to make space o grow cropsor to raisecattle,so that they can produce cheap oodlike palm oil and hamburgers.

WhatCanWeDo?If we keep our planet clean and use fewer fossil fuels toreduce global warming, we will savemillions of plants.\il7emust also use fewer trees. 7e can use esspaper andrecycle t. Some charitiescollect money to buy trees okeep them safe. $7e an pay people to care for trees anduse them in different ways to make money. For example,farmers can sell nuts from their trees. il(/emust stopcompanies destroying rainforests to bring us cheap food.\7e can plant new trees.Countries and big companiescan alsoreplace he trees hat they use.Finland andCanada alreadydo this.

Hunters kill some animals for money. Manyelephantswere hunted becausepeoplecould selltheir ivory tusks for a lot of money. Now this hasstopped, but all around the world, hundreds ofdifferent types of animal, from insects o tigers, aredisappearingbecauseof lost habirarsor hunting.Pollution is also a huge problem for animals.WhatCanWeDo?\il7emust protect habitats, and we must keep thecountryside clean.

InAfrica there are also safari parks where touristsfrom all around the world can come and see heanimals in their natural habitat.

Zoos odayMany wild animals are kept in zoos or animalreserves. f they are rare animals, the last ones can bekept safe here.They can hdve babies and there willbe more of them again.Many modern zoos keepanimals in placessimilar to their natural habitat.Sometimes they take the animals back to theirnatural home when it's safe.Some charities work to save are animals and theirhabitats.You can pay to adopt an animal and help tokeep it safe.These giant pandas ive in a specialanimal reserve n China.

Other people hink that we cannot go back to asimpler way of living. They think that new technologycan help us to find new, clean ways to trave l andmake energy.You can see some of this new technology in newtypes of house design.These new housesdon't useany energyfrom fossil fuels, but they are stillcomfortable in very hot or cold weather.They havesolarpanels n the roof, and they are made of woodfrom forests where trees are alwaysreplaced.Do you think we should live more simply or use newtechnology?Or should we do both?

WhatCanWeDo?\7hen we go shopping, we must think carefully aboutwhat we buy. Some food that we buy comes from nearour homes.Other food comes on planesand shipsfrom far away,and we use fossil fuels to transport it.Somepeople saywe should eat more food that isgrown near to our homes. Do we need summer fruitin winter? How much of the food that vou buv wasgrown near where you live?

\7e must not be greedy.For example, no onewants oceanswith no fish in them. \7e can take somefish, but we must not take too many. Wemust becareful not to use too many of E,arth'snaturalresources oo quickly.

In our everyday ife we can all help the planet in smallways.We can reuse and recycle as much aspossible oreduce waste and pollution. We can turn off lights tosaveelectricity, and we can try not to use our cars toomuch, to reduce carbon dioxide.\$7e an give money tocharities hat care or the planet. If millions of peopledo small things, this will make a difference.ItsOurPlanetScientists hink that we don'thave much time to reduceglobal warming.
