Wales: A Land of Legends, Landscapes, and Living Culture Wales is a country where ancient legends breathe through misty mountains, medieval castles rise from green valleys, and a proud Celtic culture continues to flourish. Located to the west of England, Wales is small in size but immense in history, beauty, and identity. Geography & Natural Beauty Wales is blessed with remarkably diverse landscapes. Despite its compact area, it contains three magnificent national parks : Snowdonia (Eryri) – rugged peaks, deep valleys, and Mount Snowdon, the highest point in Wales Brecon Beacons (Bannau Brycheiniog) – rolling hills, waterfalls, and star-filled night skies Pembrokeshire Coast – dramatic cliffs, sandy beaches, and coastal paths These landscapes make Wales a haven for hikers, painters, photographers, and nature lovers. History: The Land of Castles Often called “the land of castles,” Wales is home to more than 600 castles , the highest density in Europe. Each fortress tells ...
It
doesn’t! The oxygen level of the planet has varied quite dramatically in the
last 500 million years. It was 35 per cent during the Carboniferous period, around
300 million years ago; as the climate, cooled and land plants died off, oxygen
fell to as low as 12 per cent by the beginning of the Triassic. Back then, the
air at sea level would have felt thinner than at the top of the Alps today.
Burning
fossil fuels has reduced oxygen levels very slightly – about 0.057 per cent
over the last 30 years. Deforestation only has a small effect because when
rainforest is cut down, other plants are usually grown in its place. But it’s
marine phytoplankton (plant plankton), rather than trees, that produces about
75 per cent of atmospheric oxygen. Global warming will have a significant
impact on phytoplankton, which is a much more serious threat to oxygen levels.
