英検準1級要約環境

地下水は、多くの地域で飲料水を供給し、農業を支え、工場でも利用されています。

Groundwater supplies drinking water, supports agriculture, and is used by factories in many regions. When it is pumped out faster than nature replaces it, underground water levels can fall. Artificial groundwater recharge aims to return rainwater or treated surface water below the ground through ponds, wells, or special channels during periods when water is available, storing it for later use.

雑草は作物と水分や栄養分を奪い合うため、農家は取り除かなければなりません。

Farmers must remove weeds because they compete with crops for water and nutrients. However, weeding is demanding as it requires a lot of physical work. One new method to reduce this burden is to use robots equipped with artificial intelligence (AI). As the robots move through fields, the AI compares images of plants and decides which ones are weeds. The machines then pull out those plants or spray them with a small amount of weed killer.

食品の生産では、農業、加工、包装、輸送など、多くの段階で温室効果ガスが発生します。

Producing food creates greenhouse gases at many stages, including farming, processing, packaging, and transportation. However, shoppers cannot usually tell how much greenhouse gas was emitted before an item reached a store. Carbon labels are being developed to provide this information. The labels show an estimate of a product's emissions, often by using a number, letter, or color on its package.

海岸近くにある多くの大型建物では、室内を涼しく保つために電気で動くエアコンを使用しています。

Many large buildings near the coast use electricity-powered air conditioners to stay cool. Recently, some have begun using seawater air-conditioning, or SWAC. In this system, cold water is taken from deep parts of the ocean and sent through pipes to a building. The seawater cools another supply of water, which circulates through the building and lowers the temperature of rooms without entering the rooms themselves.

太陽光パネルは通常、屋根の上や、発電だけに使われる土地に設置されます。

Solar panels are usually placed on roofs or on land used only for producing electricity. Another method, called agrivoltaics, involves installing panels above farmland while crops continue to grow below them. The panels are raised high enough for sunlight, rain, workers, and farming equipment to reach the fields. This approach is now being tested in a growing number of agricultural regions where suitable land for energy projects is limited.

養殖場の魚には、適切な時間に適切な量の餌を与える必要があります。

Fish at aquaculture farms must receive the right amount of food at suitable times. If workers provide too little, the fish may grow slowly. If they provide too much, uneaten food sinks and pollutes the water. Careful timing can be difficult to achieve consistently by hand. Automatic feeding systems are now being introduced. Sensors and cameras observe the fish, while computer programs decide when and how much food to release into each part of the farm.

多くの果物や野菜は、実をつける前に受粉を必要とします。

Many fruit and vegetable crops depend on pollination before they can produce food. Traditionally, this work is done by insects or by people who move pollen from one flower to another by hand. Recently, some farms have begun testing artificial pollination robots. These machines use cameras and sensors to locate flowers and then apply pollen with small brushes or other devices as they move through fields or greenhouses.

一部の地域の農家は、寒い夜に霜が降りる危険に直面しています。

Farmers in some regions face the risk of frost during cold nights. When temperatures fall too low, young leaves and flowers can be damaged, which may reduce the value of crops. One method being introduced is the frost-protection fan. These large fans are installed above fields and move warmer air from higher levels toward crops near the ground, helping prevent temperatures around the plants from falling too sharply.
