π You're Welcome Day – 28 th May A day of gratitude, politeness, and sincere acknowledgment 28th May You're Welcome Day gratitude politeness kindness thank you Every year on 28 th May , people around the world celebrate You're Welcome Day — a simple but powerful observance dedicated to the art of gracious acknowledgment. When someone says "thank you," the natural response is "you're welcome." This day encourages us to say it sincerely, mean it, and appreciate the act of giving and receiving gratitude.

However, the message is timeless: gratitude strengthens relationships, builds communities, and makes the world kinder.

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.
