As boss of British Airways, Willie Walsh 1 more criticism than praise
lately. So he 2 delighted with the headlines he attracted last week.
Addressing the United Nations climate-change meeting in New York, Mr. Walsh promised that by 2050 the industry would cut its carbon emissions to 50% of 2005 levels through technological innovation, more efficient operations and economic instruments, such as emissions trading. Given that the industry, which is already responsible for nearly 3% of global emissions, expects to grow by about 5% a year, it was a remarkable statement.
How seriously 3 it __?
Quentin Browell, an environment specialist, insists that the pledge to make deep cuts in emissions is both real 4 feasible: “We 5 this commitment without undertaking a thorough assessment of whether it can work.” In the short term fuel efficiency is claimed 6 by 25% by 2020, 7 new flying techniques and better air-traffic-control regimes could also produce large cuts in emissions. The industry is also ready to accept a 8 increase in annual costs as a result of being brought into a global emissions-trading scheme.
Apart from carbon offsets and efficiency gains, the industry is pinning its hopes
on algae-based fuels as a substitute for today’s kerosene-based ones. Mr. Browell says 9 could eventually be responsible for cutting carbon emissions by up to 80%. He points to the success of several test flights 10 biofuels. The
certification of such fuels for aviation next year should lead to a ramping up of
production.

A bear is a true symbol of the wildlife. A bear is a very large and powerful animal well known to anyone. They are usually quite furry and can be brown or white (polar bears); even a panda can be called a bear.
For a human meeting a bear can be extremely dangerous, but in normal life, they are very calm and quiet, looking for some food and raising their baby-bears. Nevertheless, a mother-bear often avoid leaving its child with a father-bear as it can be quite dangerous too.
Depending on a habitat, their diet can vary significantly, but in most cases it consists of fish, roots, berries and other food can be found in a forest (or in a snowy area if we are speaking about white bears).
It is very interesting that bears, even if they are grown up, prefer to stay close by to their parents as long as possible.
Bears eat a lot in the summer and autumn to gain weight (mainly fat) to survive in winter, when it is impossible to eat regularly.
Медведь – настоящий символ дикой природы. Это очень большое и сильное животное, знакомое каждому. У медведей густая шерсть; они могут быть коричневыми или белыми (полярный медведь). Даже панду можно назвать медведем.
Для человека встреча с медведем может быть крайне опасна, однако в обычной жизни они тихие и спокойные: ищут еду, воспитывают медвежат. Тем не менее, мамы-медведицы предпочитают не оставлять медвежат со своими отцами, так как это тоже небезопасно.
В зависимости от места обитания, рацион медведя различается, но в основном он состоит из рыбы, корней, ягод и других съедобных продуктов, которые можно отыскать в лесу (или в снегах, если говорить о полярных медведях).
Интересно, что даже взрослые медведи предпочитают оставаться как можно ближе к своим родителям на протяжении всей жизни.
Чтобы выжить зимой, когда невозможно регулярно находить пищу, летом и осенью медведи очень много едят и откладывают жир.
